Wind energy is one of the fastest-growing segments of the energy production industry in the United States. A manufacturer makes several sizes of wind turbines. Wind turbine blades are mounted on a tower that is made of three sections. The bottom section of the tower is modeled by a cylinder with diameter 15 feet. The table gives information about wind turbines.
Energy produced by each wind turbine depends on the local wind speed. The monthly energy production for one of the wind turbines is shown in the graph.
